SDET API with Python - Warsaw (Hybrid)
SDET API with Python - Warsaw (Hybrid)
Join our Test Engineering team and drive quality for complex backend systems.
We're looking for a mid Test Automation Engineer who takes ownership, thinks beyond the test case, and thrives in a fast-paced, automation-first environment. You'll work on a backend-heavy product area, ensuring reliability, coverage, and speed - from API level to CI/CD.
Role Overview
Must-Have Technical Skills
Strong Python - clean, maintainable test code & utilities
API/backend testing with Pytest (fixtures, parametrization, assertions, test organization)
CI/CD experience (Jenkins or similar) - pipeline integration, flaky test troubleshooting, reporting
End-to-end debugging - logs, root cause analysis, reproduction
Linux basics (shell, environment, debugging) + SQL basics for data validation
Nice-to-Have (Desired Skills)
UI test automation with Playwright (page objects, stable selectors, async handling)
Experience testing REST / microservices across varied stacks
Practical use of GenAI tools (Copilot-like assistants) to accelerate test development while maintaining quality
What You'll Do (Responsibilities)
Own quality for a backend-heavy product area - aim for ~80% automation / 10-20% manual where needed
Design robust automated coverage for business flows, including integration with partner systems
Integrate tests into CI/CD pipelines, reduce flakiness, and improve feedback speed
Debug failures end-to-end, validate assumptions, and drive root cause analysis
Work proactively - spot gaps in coverage, stability, or process and improve them without being asked
Communicate clearly - write concise updates, defect reports, and explain risks to engineers and stakeholders
Collaborate with Dev, DevOps, and Product in agile teams - participate in design discussions and quality strategy
What We're Looking For (Mindset & Fit)
Quality-first mindset - challenges assumptions, prioritizes customer impact and reliability
Balances speed with robustness - knows when to automate and when manual testing adds value
Follows through - takes ownership from discovery to resolution
